Torque for all 3/8 inch locknuts (jam nuts) on the rod ends ... 14 ± 4 N·m (10 ± 3 lb ft)

Torque for all 3/8 inch locknuts on the rod end ballstuds ... 25 ± 7 N·m (18 ± 5 lb ft)

Note: All rod assembly measurements must be made in a straight line between the centerlines of the rod end mounting holes.

(10) Assembled length of link assembly ... 471.0 ± 1.0 mm (18.54 ± 0.04 inch)

(11) Assembled length of link assembly ... 367.0 ± 1.0 mm (14.45 ± 0.04 inch)

(12) Assembled length of link assembly ... 113.0 ± 1.0 mm (4.45 ± 0.04 inch)

(21) Assembled length of link assembly ... 504.5 ± 1.0 mm (19.86 ± 0.04 inch)

(22) Assembled length of link assembly ... 387.5 ± 1.0 mm (15.25 ± 0.04 inch)

Procedure for Adjustment of Parking Brake

  1. Place parking brake lever (16) in the down position (brake ON). Adjust rod (15) until the rod fits freely in lever (16) .

  1. Tighten locknut (14) on rod (15) to a torque of 5.0 ± 0.5 N·m (45 ± 5 lb in).

  1. Pull up on lever (20) until resistance is felt. Adjust rod end (18) until pin (17) fits freely in the rod end. Shorten rod assembly (19) by turning rod end (18) down two full turns.

Procedure for Adjustment of Transmission Control Linkage

  1. Place shift lever (13) in position, as shown. The control lever must be centered in the slot. See view (A-A) of Illustration 1.

  1. Position lever (23) in NEUTRAL. Lever (23) is on the transmission valve for speed control. See detail B of Illustration 1. Adjust rod end (9) on rod (5) until the stud fits freely into rod end (9). Adjust rod end (9) on rod (5) until bolt (1) fits freely into lever (2).

  1. Position lever (24) in FORWARD (F). Lever (24) is on the transmission valve for direction control. See detail B of illustration 1. Adjust rod (6) for a free fit of bolt (3) in lever (4). Adjust the rod until bolt (8) fits freely in rod end (7) .
